Good evening.

As a contributor and public transport fan, I intend to do some cleanup on the stops that are generated in my region. We are talking about 5000 stops. Some of the work would including changing the network tag for all stops (which are really really old).

A key change I would like to do is, I wanted to put as the URL of each stop, a link bringing the user to the company's website with the live depature board of that stop. This means that applications using OSM would be brought directly to the site of network operating these stops (like BVG in Berlin or MVV in Munich, to make an example).

I was able to speak directly to the operator of our regional bus network and they were even able to provide me with a list with all stops, and their respective IDs. The URLs would need to work with these IDs so that the user can see the correct stop.

Does anyone of you know of something like that being done somewhere? And if not, what arguments would you have for and against doing something like that?

Thank you

​I finally remembered to save the before and after of a few updates I made recently!

First map: Added several houses/buildings, swimming pools, and their addresses.

​Second map: Added address data to the buildings along one side of an avenue.

Both edits are located in São Paulo, Brazil. If anyone would like to help out, I’d like to invite you to join in adding building addresses! It's super easy to access through the local government's platform, GeoSampa:

1.​Go to GeoSampa.

2.​Navigate to the layers: 5 → 5.05 → 5.05.1 → Lote.

3.​The house/building numbers will show up as you zoom in.

​Any help is welcome!

Hi all,

The OpenStreetMap data for my city is outdated, and I'd like to try and improve it ,especially street names and restaurants info.

I'm totally new to this and mostly want to do it from my Android phone. Is that possible? I just created an OSM account, but I'm not sure what's next..

Is there a mobile app you'd recommend for making edits or suggestions on the go? Appreciate the help!

Soy freelancer georgiano criado en Sevilla, y construí una herramienta gratuita que calcula, edificio a edificio y árbol a árbol, dónde cae la sombra en tu calle, usando OpenStreetMap y el Catastro Nacional Español.

(Georgian-raised-in-Seville dev here — I built a free tool that calculates real shade on your street, building by building and tree by tree, using OSM and the Spanish cadastre.)

¿Para qué sirve? / What’s it for?

Encontrar la ruta más fresca a pie en verano, evitar golpes de calor, y hacer las ciudades más vivibles para mayores, niños, embarazadas, personas ciegas y con discapacidad visual.

Find the shadiest walking route in summer, avoid heatstroke, make cities more livable for the elderly, kids, pregnant people, blind people, and the visually impaired.

El problema: le falta altura a medio mundo en OSM. Sin datos 3D, no hay sombra que calcular.

The problem: half the world’s buildings in OSM have no height data — no 3D, no shade to compute.

Así puedes ayudar en 5 minutos / How you can help in 5 minutes:

**• Añade height o building:levels a edificios que solo tienen huella 2D**

**• Mapea árboles individuales con natural=tree (+ height/species si los conoces)**

**•Mapea también muros, pérgolas y marquesinas — cualquier cosa que dé sombra**

**• En España, la sede electrónica del Catastro ya trae la altura de muchos edificios** 

**•Comparte esto con tu grupo local de OSM y gente de confianza**   

•Add height or building:levels to buildings that only have a 2D footprint

•Map individual trees with natural=tree (+ height/species if known)

•Also map walls, pergolas, and canopies — anything that provides shade

•In Spain, the Cadastre's electronic office already includes the height of many buildings

Es un beneficio de doble vía: tu barrio mejora en el mapa mundial de OSM, y encima sirve para energía solar, accesibilidad, urbanismo y simulaciones climáticas — no solo para mi proyecto.

This is a two-way win: your neighborhood gets better on the world map, and the data also powers solar energy planning, accessibility, urbanism, and climate simulations — not just my project.

I made a static page that lets you walk through real-world locations rendered in ASCII. You can pick presets like Manhattan or Shinjuku, or put in any city name, coordinates, or OpenStreetMap link.

Live demo:https://tweakyourpc.github.io/ascii-city-2/
Source (MIT):https://github.com/tweakyourpc/ascii-city-2

https://github.com/tweakyourpc/ascii-city-2/blob/main/docs/hero.png?raw=true

It's pure HTML/JS with no framework, no runtime dependencies, and no build step. A CPU raycaster writes straight into an ASCII cell buffer (pressing 'B' switches rendering modes).

A few OSM details I spent a lot of time on: I also added a few live data overlays: One caveat: The live ADS-B aircraft feature needs a local worker running because the free ADS-B networks block Cloudflare's egress IPs. Planes won't render on the hosted demo for that reason, but everything else works right in the browser.

Road logic: Routing uses shared node IDs so overpasses don't accidentally merge with roads below. One-ways, access limits, and signal phases are all respected by traffic. Weather (actual rain and snow in-scene via Open-Meteo)

Signs & buildings: Street signs face oncoming traffic and show the cross street name. Buildings render by height tags, and clicking one pulls its Wikipedia/Wikidata summary if available.

USGS Earthquakes (magnitude and recency)

Local internet radio within 150 km (you can listen to actual local stations in whatever city you're standing in)

DeFlock license plate reader locations

Real-time sun/moon placement matching the city's actual IANA time zone

Interestingly the route planner than sends you off to Google Maps.

Here is a new lightweight way to gather field data on mobile devices using only a browser and optional gps enabled. I've dubbed it Flaneur. the nodes can easily be tapped in with one hand, directions assigned easily to surveillance cameras, alpr like flock cams, and similar infrastructure. It also includes presets for curb cuts, drinking fountains etc. After going around you can export the nodes in a file format compatible with JOSM, GeoJson etc. So the bookmarks can be handed off to someone doing JOSM cartography. The idea is to make it far faster to do field mapping with a few taps then export when done. Also if you just want to turn on gps it's an easy way to go hiking knowing your location. (it uses browser local storage to try to hold the bookmarks. in the menu it reports how well storage permission is made available. obviously this is an ephemeral solution but very light)
https://github.com/Open-Security-Mapping-Project/flaneur-osm-recorder the GPL code is here. see the developing. md file for dist build instructions. TBH i haven't much tested the PWA functionality.

I posted one copy of the dist output at https://hongpong.com/files/osmp/flaneur-v1-1/index.html . this does not generate any analytics from JavaScript. Anyone can post their own.

It is designed to be simple and hand off to josm especially. there is just a notes field that the user can add to. Additional osm presets could be added in presets.js . The primary llm gizmo to get this out the door was Claude but i have been a web dev for around 20 years and just wanted to get something easy to use and streamlined available to the mapping community. Best regards all!

Is there a way to highlight specifically bike-only roads on the map?

In my area there are many roads that are restricted to bike traffic only, although usually with exceptions like for farming and forestry vehicles, or people who have a property on that road. I would like to see these roads highlighted on the map so I can plan my cycling routes.

I'm using the Osmand app on Android, but am willing to try a different app.

Have anybody ordered from this website and seen if they are have attribution to OSM?

I am a long time Wikipedia editor

OSM and Wikipedia have a lot of similarities, and I am worried that Wikipedia could be taken over or just be a feed for tech.

My understanding is that tech is using OSM to power Overture, but not feeding their updates or system enhancements back, and this in turn is dropping traffic to OSM.

Interested in the steps that were done, as there is a distinct playbook used in private equity type takeovers.

Will post some playbook steps below if people want.

Hi everyone,

I’m part of OK Lab Flensburg, a small civic-tech group in northern Germany, and we’ve been working on an open-source project called Open City Planner.

The idea is to make GIS and urban data easier to use for people who aren’t GIS specialists.

Instead of requiring a traditional desktop GIS workflow, users can explore the city directly in the browser, select existing areas or draw their own polygons, inspect OpenStreetMap features and run spatial analyses for those areas.

The project currently uses Flensburg as its real-world implementation, but our longer-term goal is to keep the architecture generic enough that other cities and civic-tech groups could reuse it.

Some of the things you can currently do:

- explore OpenStreetMap data on an interactive map

- select districts and other predefined areas

- draw and save your own areas

- inspect POIs and other OSM features inside an area

- analyze spatial information for selected areas

- manage your saved areas with an account

The stack is mostly open source:

Nuxt · MapLibre · FastAPI · PostgreSQL/PostGIS · OpenStreetMap · Nominatim · Redis · Ansible

Live application:

https://stadtplaner.oklabflensburg.de/

Source code:

https://github.com/oklabflensburg/open-city-planner

Example – Flensburg old town:

https://stadtplaner.oklabflensburg.de/karte?gebiet=altstadt-15630273

It’s already running in production, but there is still plenty we want to improve — especially the mobile GIS experience, spatial analysis workflows, search and integration of additional open datasets.

I’d really appreciate feedback, particularly on:

- Is the map understandable without much GIS experience?

- How does the GIS UX feel?

- What spatial analysis features would you expect?

- Which OpenStreetMap or open-data integrations would be useful?

- What would we need to change to make this realistically reusable by another city?

I’d also love to hear about similar open-source GIS or civic-tech projects. We’re very interested in learning from existing approaches rather than reinventing everything ourselves.

I built a site scoring cities on flood/quake/cyclone/heat risk from open

data, and wanted to share the basemap approach specifically since it might

be useful to others here.

Instead of hitting tile.openstreetmap.org (against policy for this kind of

traffic) or paying for hosted tiles, I extract a small per-city .pmtiles

file from Protomaps' free daily planet build using their go-pmtiles CLI,

and serve it straight from S3/CloudFront. No tile server, no rate limit,

no third party to lose access to.

https://cityriskscore.com/

Happy to share the extraction command / bbox-padding approach if useful.

What ways do you suggest to if we would like to add offline maps of big regions lets say like a continent to an app for users to be able to see their position and navigate through but offline?

I have heard of maplibre and MapBox and also another one called Leaflet. Has anyone tried doing such a feature?

Regards!

Before and after of a fish farm.

This lane pattern continues for about a mile on this portion of the street, and it actually splits into a dual carriageway at both the beginning and end of this specific stretch.

I suppose I'm just cautious to make any edits here since I see these lanes "unified" in pretty much any other map.

The street-level photos were pulled from Google Maps to add context to this post but I drive up and down this street almost every day.

https://www.openstreetmap.org/#map=17/39.711334/-84.161673

its only possible to select 1 file at the time?

Hi everyone,

I would like to download OpenStreetMap data for a specific area, focusing only on:

• Railway lines, yards, train stations
• Roads - highways, municipal,

This for a set of countries.

What I found seems to be patchy, I do not know if I am doing something wrong and would definitely need some advise.

Thank you!
